Estates are kept a lifetime.

Our floorplans suit a family from the day their first child arrives to becoming empty nesters because we plan for the way a family's use of rooms evolves over time.   And our approach to design defies aging because we fuse the best of architectural features that have withstood the test of centuries with the clean, simple aesthetics of modern lines.

At KCS Estates we are mindful of our homes' lifetime impact on our environment. Our strongest  concern centers around  our homes' consumption of our scarce natural resources.  Learn more about our Green Building practices.
